Brass Door Furniture FAQ


Brass
first became available as early as 1585 in the form of brass lattens, which were
a solid block of brass that could be shaped into various household items such as
bowls and basins etc. Although brass was available as early as this time, actual
brass door furniture was not produced until 1595 and the brass was made from an
alloy of copper and calamine. This brass was not cast easily and was very red in
colour, similar to copper. It was of poor quality and had a bubbled and pitted
appearance.
From 1690-1710, lead was added to the copper and calamine alloy resulting in a
much softer brass that was easier to shape, as all productions were still done
by hand. 1725 saw the invention of the spring rolling machine that allowed the
brass to be rolled into sheets and stamped to a particular pattern, but it
wasn't until 1770 when James Emerson patented an alloy of copper and zinc that
British brass became known as what it is today. From 1860 more complicated
casting could be produced allowing more intricate and ornate pieces.
Although
today we regard Georgian brass as rope effect, Regency as beaded and Victorian
as plain, in fact only the Regency style is correct. True Georgian furniture was
symbolised by plain knobs on a round rose, and it was the Victorian era that saw
the introduction of swirls and decorative styles. Today's Regency style is a
more accurate representation of furniture designs of that time. Two types of
beading were evident, a consistent small bead and a pea bead which was a small
bead followed by an elongated bead. (Looked more like a bean than a pea!!)
Brass
door furniture was considered to be an extravagance during and after the Second
World War and is still seen as being luxurious today!
Q. Why does my brass door furniture tarnish over a period of time when
exposed to the environment?
A. This is due to many factors. These include salt spray if you
live near the sea or a main road, humidity and pollution. These
conditions attack the lacquer on the furniture and break it down, therefore
there is no protection for the brass and after a while it will become
discoloured. Rings and keys can also scratch the clear lacquer coating and this
should be avoided as much as possible, once the protective coating is damaged
tarnishing and discolouration will start to occur.
Q. Should I use metal polishes
to clean my brass door furniture?
A. Brassware items that have been coated in lacquer must never be
cleaned with metal polishes or aerosol spray polishes. The lacquer coating will be
damaged and this will then cause early discolouration.
Q. Can the protective coating
be damaged by other cleaning agents?
A. Yes. As well as metal polishes it is also necessary to avoid any
abrasive cleaning liquid, chemicals or cleaning solvents as these will all
damage the lacquer coating. Wire brushes or scouring pads should also be
avoided.
Q. How can I clean, maintain
and prevent my brassware from tarnishing?
A. If your brassware is fitted on interior doors it is less likely to
tarnish, as it is not exposed to the harsh exterior environment. Regular dusting with a camel
hair brush or soft cloth should be sufficient together with an occasional wash with
warm mild soapy water, never use hot water. If, however, your brass furniture is fitted on exterior doors the process
is different. You should still dust your brassware, but it is advisable to apply
a coating of wax polish once a week, this should keep your brassware in good
condition. It is also beneficial to lubricate the mechanism with a drop of light
oil about once a year. Unfortunately, after prolonged exposure to an exterior environment the
lacquer will probably break down. If this happens the lacquer can be removed by
using paint stripper solution, acetone or even nail varnish remover, only then will your
brassware be suitable to clean with a metal polish. Mechanical polishing with
metal polish will remove any tarnishing once all trace of the lacquer has been
removed but take care not to be too aggressive especially with fine or delicate
brass. An alternative way to remove tarnishing and corrosion is to rub any
affected areas with a slice of lemon after the lacquer has been removed. The
lemon can be dipped in salt to assist the process by providing some gentle
abrasion. Be sure to wash and dry the item using warm soapy water afterwards or
the acid in the lemon may continue to attack the brass after the corrosion has
been removed.
Q. Once I have removed the lacquer, do I have to reapply a new coat of
lacquer?
A. Not necessarily, once you have removed the lacquer you can maintain
the brass quite easily with simple regular maintenance. First wash and dry your
item with warm soapy water to ensure the brass is clean. Next you can polish
with a cloth that has previously been soaked in a metal polish such as Brasso™
and allowed to dry for 24 hours. The cloth can be used more than once to clean
your brass because the polish will have soaked into the material of the cloth by
leaving it for 24 hours - this will save on polish and give a better finish!
After polishing up with a dry cloth, wipe your brass with a little olive oil. To
maintain the finish on un-lacquered brass it is simply necessary to wipe once a
week with liquid ammonia and then a little olive oil to create a hard wearing finish on
the brass that will require very little further polishing! Alternatively you could reapply a new layer of transparent lacquer and clean as
mentioned in the previous question above. Whilst re-applying lacquer may be
appropriate for internal brass we recommend leaving the lacquer off external
brass and maintaining it as described here. In the case of genuine antique or
very delicate brass please refer to the next question.
Q. I have antique brass pieces
and wish to maintain them without damaging the surface, what should I use?
A. To clean antique brass pieces firstly wash them with warm soapy
water and then dry. Make a paste using whiting and boiled linseed oil then use
this to clean your pieces. This is a soft paste and so should not damage the
antique look of your brass. As with all cleaning processes, check your method on
a small hidden area first to ensure you are achieving the desired results. A
whiting and boiled linseed oil paste could also be used as an alternative to
metal polish in the previous question, especially on fine delicate pieces.
Q. Are there better qualities
of lacquer which will stop my brass from tarnishing?
A. High quality brassware, which includes most of the range sold at our online
store, are protected by a process known as electrophoretic lacquering. During
this process the article is suspended to form the cathode in the electrophoretic
process, the anode is plain stainless steel. A voltage is applied and positively
charged microscopic particles migrate towards the workpiece and plate onto it.
Being non-conductive, these particles progressively insulate the area already
covered causing the current to flow in uncovered areas. An even coating of a 5
to 10 micron layer is achieved and stoving at 125 to 150 ºC completes the
process. This process has significant benefits over conventional lacquer as
follows:
-
High gloss and good solvent resistance
-
Greater pencil hardness
-
Can withstand greater hours in salt spray test
-
It adheres 100% on the coated surface
-
Improved solvent resistance
-
Humidity cycling does not affect adhesion or appearance for a prolonged
period
-
Helps in avoiding drip and tear marks
-
Environment friendly
-
Improved chemical property
-
Ultra violet radiation resistant
Brassware made with this process will certainly last longer before it
discolours when compared to a conventionally lacquered product. Please email us

Q. Is there any such thing as non-tarnishable brass?
A. There is indeed a product that has a guaranteed promise that your
brass will not tarnish! This product is called Everbrite™ and is
available on our online store. It is more expensive than other brassware but
your door furniture will look the best in the street and your neighbours will be
wondering how your brassware always stays so bright and clean. Everbrite™ uses
a process called physical vapour deposition to achieve its durable
finish, this involves depositing molecules of durable metals onto the brass
surface. This microscopic layer protects the brass from becoming discoloured and
tarnished when exposed to pollution, sunlight and coastal areas. Everbrite™
are so confident they offer a 25 year guarantee on the finish of this brassware,
even when exposed to harsh environments.
Q. Can I mix Everbrite™
brass and lacquered brass around my house?
A. Everbrite™ brass is slightly richer in colour to lacquered brass
and, because there is no lacquer on the surface of this finish, it has a
brighter polished shine. Whilst the two products are very similar and certainly
don't look out of place next to each other, they would not be a perfect match on
the same side of a door. It should also be considered that the finish on
lacquered brass may deteriorate with time, whereas the Everbite™ would not,
and as a result the slight difference in appearance could become exaggerated.
If however the products were used on different doors in the same house it would
be difficult to spot the difference. Many people therefore use Everbrite™ on
the external side of their front and back doors (were corrosion is most likely
to occur) and standard lacquered brass internally. It could also be considered
for bathroom doors and is ideal for marine applications where we recommend that
the handle's mechanism is well greased before fitting. Some people like the
Everbite™ finish so much they have fitted it throughout their house! The images
below show Everbite™ products on the left and polished brass on the right.

Q. Why haven't I bought the Everbrite™ door furniture?
A. That's a very good question, why haven't you bought the Everbrite™
range yet? If you have any reason why you wouldn't buy it please email
with your feedback.
Q. How is the Heritage brass
locking casement stay fitted?
A. The following series of diagrams shows how this stay locks into its
keep. (Note this stay does not use a key, the stay interlocks with the keep)
